WATER HEATER.

Application filed March 24L, 1922. Serial No. 546,217.

To all 207mm it may concern:

Be it known that I, WLAnisnAw SLnsnN- SKI, a citizen of Poland, residing at Hamtramck, in the county of Wayne and State 5 of Michigan, have invented certain new and useful Improvements in Water Heaters, of which the following is a specification.

Primary among the objects of this invention is to provide a water circulation system having connections with a hot water boiler of conventional type, the water heating elements being adapted to conform with the interior walls of the fire pot of a stove, range or furnace.

Another object is the provision of means whereby the water heating coils of the sy tem are adapted to be vertically adjusted to agree with the varying depths of diiierent fire pots.

A further purpose relates to means employed whereby individual coils of the heating element are provided with flexible joints adapted to allow vertical movement therebetween.

These and other like objects are attained by the novel arrangement and combination of parts hereinafter described and shown in the accompanying drawing, forming a terial part of this disclosure, and in which Figure 1 is a front elevational view of a range, partially in section showing the device made in accordance with the invention and connected to a water boiler.

Figure 2 is a longitudinal sectional plan view thru the fire pot showing one of the heating coils.

Figure 3 is a vertical sectional view of the same showing a modified arrangement of the coils and means for adjusting same.

Figure 4: is a longitudinal sectional view taken on line 4:--4 of Figure 3.

Figure 5 is a fragmental elevational view of the fire box front grate.

Referring to the drawing, the numeral 10 designates a domestic stove or range having a cooking oven 11, a fire box 12, fitted with suitable end linings 13 and 14-, a similar back lining 15, a front fire grate 16, and 5 3 a bottom grate 17 supported above an ash pit 1s.

A conventional hot water boiler 19, shown adjacent the ends is held and supported by the column support generally indicated by the numeral 20.

32 and 33 are interposed between the upper Thru the pipes 21, 22 and their angular connections 23 communication is efi'ected with a plurality of a-ngularly disposed tubular elements 24 connected at their ends with elbows 25 fo'rmingoblong rectangular coils, arranged in adjacent order one above the other and connected at alternate ends to form a continuous water passage from the supply pipe of the boiler, thru the coils and return to the boiler.

The inlet of the lower coil is secured rigidly thru the end walls of the range and the lining 13 by a nut 26 screw-threaded on the pipe of the lower coil 24-, and a raising block 27 at the opposite end of the fire box 12 maintains the coils in an angular position.

From the "foregoing it will be seen that a simple and efficient device has been disclosed for heating water for domestic and other purposes, particularly where it is desired to heat quickly larger volumes of wa ter. The iarrangement of coils gives a. greatly increased area of surface in direct contact with the fire and assures a rapid continuous circulation thru the system.

The modification, shown in the Figures and 4, discloses similar oblong rectangular heating coils 30, provided at their angular corners with spring controlled movable joints forming right angled flexible connections 31 adapted to allow the individual coils to be raised vertically, thus increasing the space between adjacent coils and providing means whereby the height of the coils may be adjusted to suit the depth of the fire pot.

To compensate any vertical movement of the coils 30, water-tight flexible connections coil 30 and the boiler return pipe 34.

The elevating principle of the device is particularly advantageous when in the event of an accumulation of ashes above the grate, a relatively cold area is presented adjacent the coils which may be raised upward into the area of hot coals.

Means for adjusting the coils being thru a system of pivoted levers forming lazy tongs, these levers 35 crossing at their centers, are secured by pivots 36 fixed rigidly to the longitudinal center portion. of the side coil elements 30, and the ends of the levers 35 are secured together in pairs by pivots 37. The lowermost pair of levers are provided at the outer ends with slots 38, within which operate studs 39 fixed to the inside of the vertical grate 40.

A handle 41 passes rotatably thru the grate 40 and is provided at its inner end with a cam 42 so positioned as to make contact with the underside of the lower center pivot as the handle 41 is turned, the cam, acting against the pivot 35, causes the coils to be raised; on reversing the motion of the handle, the coil returns to normal position by gravity.

The foregoing disclosure is to be regarded as descriptive and illustrative only, and

r not as restrictive or limitative of the invention, of which obviously an embodiment can be constructed including many modifications, without departing from the scope of the invention as defined in the claims hereto appended.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A water heating system comprising a boiler and a ran e hav-in tubular connections therebetween, oblong rectangular coils disposed within said range, flexible articulated joints formed at the corners of said coils, lazy tong levers pivotally engaged with said coils, means whereby said levers cause thecoils to raise and become equally separated one from the other, and flexible compensating elbow joints communicating between said boiler and coils.

2. A water heater comprising coil members disposed within the fire pot of a range or the like, said coils consisting of tubular elements joined at the corners by flexible articulating elbows forming a continuous passage therebetween and adapted to be raised and lowered, lazy tong levers pivotally connected to said tubular elements, and means for operating said levers.

3. In a water heating device, the combination with jointed coils disposed within the fire box of a range or the like, means for raising and lowering said coils into positions of greatest heat area, lazy tongs pivoted to said coils, means for operating said lazy tongs exterio'rly of the range, and means for compensating the different vertical adjustments of said coils with respect to the fixed connections entering into said fire pot from a boiler. y

In witness whereof I affix my signature.
